Question

x equals 2, what does y equal ? -3x - 8y = 10

Answer 1

$Given \: x = 2 \\⇝ - 3x - 8y = 10 \\⇝ (- 3 \times 2) - 8y = 10 \\⇝ - 6 - 8y = 10 \\⇝ - 8y = 10 + 6 \\⇝ - 8y = 16 \\ ⇝y = \frac{16}{ - 8} \\⇝ y = - 2$

∴ y = -2

Answer 2

Answer:

y=-2

Step-by-step explanation:

-3x-8y=10

since,x=2

》-3×2-8y=10

》-6-8y=10

》-8y=10+6=16

》y=16/-8=2/-1

to ratisionalize it we will multiply both denominator and numarotar by-1

we will get

2×-1/-1×-1=-2
